2 DPT - Target Type Flowmeters Features Patented Target/Leaf-Spring Minimal Wear Components to GPM Water Accuracy ±3% of Full Scale Line Sizes 3/8 to 3 Wide Variety of Wetted Materials The DPT series uses a unique, patented target system to measure the flows of liquids. This design uses a single leaf-spring to both suspend the target and to provide the target resetting force. The use of a single leaf-spring is a simple, reliable design which allows for operation with virtually no wear. DPT Series Target Type Flowmeter Specifications Displays and Controllers: Flow Range: Liquids: GPM through GPM water DPT-C: Compact LED display with switch and 4-20 ma flow transmitter DPT Series Measuring Principle The mechanism consists of a target plate (1) and lever arm (2). Fluid flow causes the target plate and lever arm to deflect against the leaf-spring. A permanent magnet (3) attached to the lever arm and Hall effect sensor (4) mounted inside the display unit translate the angular motion of the target to an electrical signal. The signal from the Hall effect sensor is used by the electronic indicators to provide a flowrate display, adjustable setpoint switches or an analog flow signal. The DPT series is available in bronze or stainless steel bodies from 3/8 inch through 3 inches. The target plate measuring system offers a very low head loss and is immune to problems caused by fluids with high solids content.
